结合笔者的工作,对国内外高温超导家族中,Y系、Bi系、T1系和Hg系等各个材料领域的成材发展现状作了简要综述,认为PITAg包套技术有其独到之处,并已取得了现实意义上的进展,最近的工作也仍然很活跃,双轴离子辅助的过渡层技术(PLD+IBAD)确已获得了诱人的Jc指标,但面临实际应用还有一定困难,压延辅助(RABiTS)的人工结构技术为获得实用型高温超导带材提供了新的思路,原则上也适用于高温超导家族中的各种材料领域。在今后的研究工作中,如能制备出长尺寸、具有强烈双轴织构的基带,相信会进一步提高Jc。因此很有进一步研究的必要。
Based on the author’s work, a brief review is given of the current status of the development of various materials such as Y series, Bi series, T1 series and Hg series in domestic and overseas high temperature superconducting families. The PITAg package technology is considered as unique Progress has been made in the practical sense, and recent work is still very active. Bipolar ion-assisted transition layer technology (PLD + IBAD) has indeed acquired attractive Jc index, but there are still some difficulties in practical application. Rolling assist RABiTS) artificial structure technology provides a new idea for practical high-temperature superconducting tapes, in principle, also applies to a variety of materials in the high-temperature superconducting family. In the future research work, if we can produce a long, strong biaxial texture of the baseband, I believe it will further improve the Jc. So there is a need for further research.
